A signal processing apparatus includes a signal generating block arranged to generate a target estimated signal of a specific signal component in an input signal. The signal generating block includes a reference signal generating circuit, a signal processing circuit, and a signal adjusting circuit. The reference signal generating circuit is arranged to generate a reference estimated signal for the specific signal component in the input signal. The signal processing circuit is coupled to the reference signal generating circuit, and arranged to process the reference estimated signal and accordingly generate a signal processing result. The signal adjusting circuit is coupled to the signal processing circuit and the reference signal generating circuit, and arranged to output the target estimated signal by adjusting the reference estimated signal according to the signal processing result.

Signal processing apparatus and related method for generating target estimated signal of specific signal component in input signal

A configurable calculating circuit includes a multiplexer, a mixer and an accumulator. The multiplexer is for receiving input signals including at least a first and a second input signals, and selectively outputting at least one of the input signals. The mixer is for mixing a selected input signal outputted from the multiplexer with a local oscillation signal to generate a mixed signal. The accumulator is for accumulating the mixed signal to generate an accumulated signal. When the configurable calculating circuit is operated under a first mode, the multiplexer selects the first input signal, and the accumulator performs a first accumulating operation upon the mixed signal; and when the configurable calculating circuit is operated under a second mode, the multiplexer selects the second input signal, and the accumulator performs a second accumulating operation, different from the first accumulating operation, upon the mixed signal.
